I created a custom post-type called "designs" for this case. So I want the client to go to his backend and click "Create new Design", this will open up the create page screen, now I want my client to have the option to just upload a number of PDFs and I want to be able to put those PDFs in a layout I desire.
Right now, with wordpress' default behaviour the user can upload PDFs but they will appear as text links and he can just add his own formatting of the page in the editor.
So my question boils down to this: 1) how am i able to limit the user to just inputting his PDFs and thats it?
Bonus question: Is it also possible to somewhere state implicitly that the PDF has to open in a new tab?
